|This invention vrelates :generally to Aa-rtijulated locomotives, fandhas :for 4an object the provision of :a locomotive structure 'embody- King at least two longitudinally .spaced len-k gines, each comprisingtwoduplicate'castings, each 'casting having a 'lhalf:'s'addle,'a workingcyl-inder,and a distribution vvalve chest, 'the half saddles being soformed at 'their ltops that when combined vthey will provide vahorizontal fshe'lff adapte'd to A'support either Ia boiler xbearing'orfa platform, fall *of the half saddle fandcylinder `castings being ofthe same form and 'interchangeableone with the other.

Another object of the 'invention .is "to `profvide a locomotivestructure embodying fat least two .longitudinally spaced engines, eachengine comprising in an integral "casting :a plurality -of working'cylinders, 5a vplurality 'go of distribu'tionvalve chests, and a4vcylinder saddle, the 'cylinder saddle being formed 'at itsftop with ahorizontal shelfadapted to support either 'a boiler bearing Io'raplatfo'rrn, the'two castings being duplicates andfinterl 425 changeableone with the other.

' @ther objects Alof fthe invention will hereinafter readily appear. Y v

The improvement claimed is hereinafter fully set forth. i f

In the practice of the invention, referring vto the specific embodiment4thereof selected -for eneinplication herein, the locomotive coin-prisesa boiler 10, a front main frame section ll, articulated to a. rearmainframe section '12.' Supported on the front end of the rear mainframe section 12,-is a'steamfen-y gine i3, `and supported on thefrontend of the front main frame l'l,r is a` steam `'engine 114. Eachsteam engine embodies 'two Adupli- `cate castings, each-casting1comprisingra workiing cylinder 15.; adistributi'on valve rchest 116; ahalf saddle :17; a flanged steam `deliv- 'erypassage 18, leading-to `thevalve chest `gian exhaust passage .19,y leading from the valve vchestthrough the saddle from "the frontend thereof to vthe Vrear end thereof;a plug `20, closing one 4end of the exhaust passage; and a flathorizontalishelf portion 21 at the top .off-*the saddle. When two of thecastings 'are combined to form an engine, the shelf portions 21 `thereofconstitute a flat shelf 22 Vadapted-to support either a boiler bearingor 'al platform. Mounted on the shelf 22o'f fthe lengine 13 is a boilerbearing 23, yandniounted on thefsh'elf'22 ofthe engine 14 is a lfiatrplate :or platform 24. .The inner end ofeach `half saddle is formedwith a guide recess 2,5 for a v centrally 4disposed .reverse gear reachrod L26.

hen 'itv is desired 'to transfer vone of the cylinder vand half saddleycastings from one side of'thelo'comotive to the'other, the closureplugQO a'tone end'of the exhaust portinaybe transferred to the oppositeend thereof.

The cylinder and half lsaddle castings fof the same pattern, and thenumber of stock 7 ofthe drawings, lthere ane combined in `a castingsyrequired Vfor vreplacements to be greatly reduced. -In'the modificationshown in Figs. 6 fand @Oat 'the top vof .tlie'saddlc, adapted Q $11,191dem illustrates the casting of the front engine, on j the shelf 30 ofwhich'is supported a platform 33.

While but two forms of construction have been described and shown, it isobvious that many variations in procedure, form, arrangement, andconstruction of parts, may be resorted to, and the invention, therefore,is not limited to the particular embodiment disclosed, but includes suchchanges and modifications as vcome within the spirit and scope of theinvention as set forth in the appended claims.
